Taking you money and does not want to refund you

On the 7th of March my account was incorrectly debited and Rain 5G acknowledge the mistake due to a technical error that occurred on their side. They promised that the Money would be refunded and back in my account on the same day. Then I got told that the reversals takes anything from 7 - 10 business days. We are currently on the 14th Business day and the money is still not back in my account. I have spoken to so many people at Rain but no one seems to care. They don't care that I could not feed my family. They don't care to help you. Rain is the worst company.
